I'm using TypeORM with JS and it's docs are super minimal, so I couldn't find the solution for my question over there. I want to create a one-to-many bi-directional relationship and can't get over the following exception:

TypeORMError: Entity metadata for Team#groups was not found. Check if you specified a correct entity object and if it's connected in the connection options.

Thats the definition of the two entities (one team might have multiple groups):

module.exports = new EntitySchema({
  name: 'Team',
  tableName: 'team',
  columns: {
    id: {
      primary: true,
      type: 'uuid',
      generated: true,
    },
    name: {
      type: 'varchar',
    },
    
  },
  relations: {
    groups: {
      target: 'TeamGroups',
      type: 'one-to-many',
      inverseSide: 'team_id',
    },
  },
})

module.exports = new EntitySchema({
  name: 'TeamsGroups',
  tableName: 'team_group',
  columns: {
    team_id: {
      primary: true,
      type: 'uuid',
    },
    group_id: {
      primary: true,
      type: 'uuid',
    },
  },
  relations: {
    team_id: {
      target: 'Team',
      type: 'many-to-one',
      joinColumn: true,
    },
  },
})

What am I missing?
